By pressing the AUTO button on the control panel, the boiler will automatically choose the ideal output for the central heating circuit by gradually increasing the power of the boiler until the room reaches the set temperature, whilst guaranteeing no excessive peaks.

When used in conjunction with the extensive range of controls, the AUTO function ensures greater levels of comfort and savings are achieved.

With the AUTO function activated and by fitting an outdoor sensor, with one of the modulating controls, savings in excess of 6% can be achieved over a standard condensing boiler without similar controls
